What is the role of IACUC-approved protocols in a mouse program?

• A. They provide oversight to ensure humane care and compliance with regulatory standards.
• B. They allow unregulated experiments if staff are trained.
• C. They are optional guidelines without enforcement.
• D. They primarily serve to document supply chain purchases.

Answer: (A)

IACUC-approved protocols provide oversight to ensure humane care and regulatory compliance in a mouse program. These protocols are formal plans that specify what species will be used, how many animals, all procedures to be performed, anesthesia or analgesia, endpoints, housing and husbandry, monitoring, and personnel training. They must be reviewed and approved by an Institutional Animal Care and Use Committee before any work begins, and they are subject to ongoing oversight through annual reviews and facility inspections. Following the protocol helps protect animal welfare by minimizing pain and distress and ensures adherence to laws and guidelines (such as the Animal Welfare Act and Public Health Service policies), incorporating principles like the 3Rs—reduction, refinement, and replacement. If changes are needed or if something deviates from the protocol, amendments or deviation reports are required. In short, the role is to provide binding, enforceable oversight that guarantees humane care and regulatory compliance, not to permit unregulated experiments, not to function as optional guidelines, and not to govern supply purchases.
